For starters here are some of the ways that you can kiss the tail on the 777 and as I reacall many of these apply to your favorite airplane, the L1011, of which I have more than a few hours as well.
To start in order of occurance:
#1 Missed trimed due to out of CG effects
#2 Miss use of the flight director
#3 Alternate Aft CG applications
#4 Early rotation
#5 Agressive rotation as in pulling on the pole
In my limited L-1011 experance, 32 years on the program and 22 of those years in customer support, I worked or assisted in 7 or 8 L-1011 tail drags. Not one of them was on takeoff they just didn't happen.
